摘要： Methods and apparatus related to supporting rapid synchronization between groups of wireless communications devices are described. Described methods and apparatus are well suited for use in peer to peer wireless communications systems in which a plurality of ad hoc peer to peer networks may be formed, each ad hoc network operating with its own notion of time. As two groups of devices, having different notions of time, come within proximity of one another, a wireless communications device of a first group detects the presence of a member of a second group. The wireless device determines that network timing re-synchronization is to be performed by one of the first and second groups and transmits a re-synchronization alert signal on a dedicated resource. Subsequently, the wireless device transmits a timing synchronization signal in accordance with new timing. Intended devices, which detect the alert signal and timing synchronization signal, adjust their internal timing.

摘要： To maintain a synchronized wireless peer group, timing signals may be periodically transmitted by one or more devices in the wireless peer group. These periodic timing signals may be transmitted by different wireless devices in the peer group, distributing (sharing) the transmit power burden among the different wireless devices, increasing the useful operation time of the individual wireless devices. Similarly, the wireless peer group may monitor for timing signals received from devices that are not part of the wireless peer group. This monitoring burden may also be distributed (shared) among the devices in the peer group allowing for a greater sleep time for individual wireless devices, increasing the useful operation time of the individual wireless devices.

摘要： Methods and apparatus related to packet fragmentation and reconstruction are described. A sequence of bits is generated including at least one header and at least partial packet payload prior to a determination of the actual data rate to be used in a communications segment. In some embodiments, the generated sequence of bits corresponds to a prepared information bit stream for a best case scenario in which the highest data rate is selected for segment. Various embodiments allow for the selection of the data rate to be used for the communications segment to be delayed until just prior to the transmission. Thus the selection of the data rate for the communications segment, and thus the segment capacity, can be based on more current channel condition information than would otherwise be possible if the communications device needed to know the data rate for the segment before performing header and packet fragmentation operations.

摘要： Disclosed are CMOS-based devices for switching radio frequency (RF) signals and methods for biasing such devices. In certain RF devices such as mobile phones, providing different amplification modes can yield performance advantages. For example, a capability to transmit at low and high power modes typically results in an extended battery life, since the high power mode can be activated only when needed. Switching between such amplification modes can be facilitated by one or more switches formed in an integrated circuit and configured to route RF signal to different amplification paths. In certain embodiments, such RF switches can be formed as CMOS devices, and can be based on triple-well structures. In certain embodiments, an isolated well of such a triple-well structure can be provided with different bias voltages for on and off states of the switch to yield desired performance features during switching of amplification modes.
